They do not appear to be symmectric. they seem to line up well
Answer:
Step-by-step explanation:
Your equation makes no sense.
I will ASSUME you mean
y = -x² - 2x + 3
which can be factored
y = (x + 3)(-x + 1)
x intercepts occur when y = 0
0 = (x + 3)(-x + 1)
which means either
x + 3 = 0
x = -3
or
-x + 1 = 0
x = 1
x intercepts are (-3, 0) and (1, 0)
The vertex will occur halfway between these point
x = (-3 + 1) / 2 = -1
so vertex = y = -(-1)² - 2(-1) + 3 = 4
(-1, 4)
15?im not sure...but I think thats right
Answer:
Step-by-step explanation:
Hello:
the equation is : y = ax+b
the slope is a : a×(2) = -1......( perpendicular to a line with a slope of 2 for : y=2x+1)
a =-1/2 y=(-1/2)x+b
the line that passes through (6, 2) : 2 = (-1/2)(6)+b
b = 5
the equation is : y = (-1/2)x+5
